Local government data, compared across jurisdictions and kept current.

The kind of question this answers

Not “how do I pay my property tax bill” — your municipality’s website already answers that, and answers it better than anyone else could. The gap is one step over:

• Is my rate high or low compared to the town next door?
• What would the same house cost me somewhere else in the province?
• Has my rate gone up faster than everyone else’s over the last five years?
• How much of my bill is actually my city, and how much is the county and the province?

Every one of those needs figures from many jurisdictions at once. No single official source publishes them that way, because no single official body is responsible for the comparison. That is the whole job here.

How every table is built

1. Official filings only. Numbers come from what each jurisdiction is legally required to report — not estimates, not projections, not an average of other people’s averages. Where a jurisdiction has not filed for a year, the row is left empty rather than guessed at.
2. Every row cites its source. Dataset, the statute that compels the filing, the tax year, and the exact file it was retrieved from, with the date it was retrieved. If a number here disagrees with your bill, you can go check which of us is wrong.
3. Kept current automatically. Source pages are watched for change. Most comparison tables on the web are correct on the day they are published and quietly wrong a year later; the difference between a useful table and a misleading one is almost entirely maintenance.
4. Reference, not advice. These are the published figures. What they mean for your situation depends on your assessment, your property class and local charges that a jurisdiction-wide rate does not capture.

What comes next

Property tax across Ontario is the first dataset because the filings are complete, the legal basis is unambiguous, and the comparison genuinely does not exist anywhere else in one place. The same method extends to anything published one jurisdiction at a time: utility rates, licensing and permit fees, transit fares, long-term care costs. Each is added only once its data can be sourced and kept current to the same standard — a broad site full of stale tables would be worse than a narrow one that stays right.
